Definitions
- This invention relates generally to child safety seats intended for installation in automotive vehicles, and particularly concerns an improved child safety seat assembly which advantageously functions in the event of severe incorporating-vehicle collision to rotate the seat occupant to a less injurious position and with reduced impact shock.
- the most frequently used child safety seat construction basically involves a forward-facing molded seat having an attached harness/belt restraint for properly retaining the child occupant in the seat and a separate seat-belt restraint for retaining the molded seat in its proper position upon a conventional seat of the automotive vehicle.
- a conventional seat of the automotive vehicle In such known child safety seat installations it is common, in the case of severe collision of the incorporating automotive vehicle, for the child safety seat occupant to experience a high degree of collision impact shock and possible or even probable consequential occupant injury.
- the child safety seat assembly of the present invention is basically comprised of a frame-like base sub-assembly, a molded seat sub-assembly slidably mounted on the base sub-assembly, and an energy-absorbing member functionally situated intermediate the seat and base sub-assemblies.
- the frame-like base sub-assembly has a restraint means for use in retaining the same in a proper position upon a conventional automotive vehicle seat, and also has a pair of arcuate, tongue like, side rail elements mounted at opposite sides of the base sub-assembly.
- the molded seat sub-assembly has a body restraint means for the seat occupant, and also has a pair of arcuate, groove-like, side rail elements that are attached at opposite sides of the seat sub-assembly and that functionally engage the corresponding base sub-assembly pair of side rail elements.
- the novel child safety seat construction of the present invention incorporates at least one energy-absorbing device such as a honeycomb core energy absorption cylinder, a foamed polyurethane block, a shock strut, or the like in the assembly functionally intermediate the seat member and the frame-like base member.
- a shear pin element in the improved child safety seat assembly as between the base member and the seat member.
- the shear pin element functions as a "threshold" control device which prevents the displacement of the seat member relative to the base member as during normal use and except upon the occurrence of substantial assembly/occupant deceleration as in the case of an automotive vehicle collision occurring at velocities above some predetermined level of magnitude.
- the shear pin device in the improved child safety seat assembly is completely sheared, the assembly seat and occupant are caused to be rotated relative to the assembly base sub-assembly to position the seat occupant in a more reclined position, and a portion of the inertial energy of the seat/occupant combination is absorbed in the included energy-absorbing device.
- FIG. 1 is a side elevation view of a preferred embodiment the improved child safety seat of the present invention
- FIG. 2 is a front elevation view of the child safety seat illustrated in FIG. 1;
- FIG. 3 is a section view taken at line 3--3 of FIG. 1;
- FIG. 4 is a section view taken at line 4--4 of FIG. 2;
- FIG. 5 is a side elevation view illustrating the improved child safety seat of the invention in its fully-reclined position such as immediately following a severe collision of the incorporating automotive vehicle with another automotive vehicle;
- FIG. 6 is a section view similar to FIG. 4 but illustrating the improved child safety seat of the invention in its fully reclined position and with its included energy-absorbing device in a fully-collapsed condition.
- FIG. 1 illustrates the preferred embodiment of the child safety seat assembly 10 of the present invention in its customary mounted position on a conventional automotive vehicle seat 12, such safety seat essentially being comprised of a base sub-assembly 14 supported by vehicle seat 12 and a seat sub-assembly 16 supported by base 14 through the hereinafter-described co-operating, arcuate side rail elements.
- Safety seat 10 is restrained in its proper position on vehicle seat 12 a typical passenger seat lap belt 18 that passes through openings 20 in base sub-assembly 14 and that has its ends preferably secured to the automotive vehicle frame.
- seat sub-assembly 16 be molded to a configuration such as that illustrated in the drawings using a plastic material such as a polyethylene resin having high density and high impact strength physical properties. Such materials may also be utilized in the manufacture of base sub-assembly 14 although it is common to make the frame portion of sub-assembly 14 from formed and welded pieces of metal tubing 15 such as a conventional steel tubing.
- seat sub-assembly 16 is basically comprised of a molded seat element 22 and an adhesively attached molded seat pan element 24 that includes the pair of integrally molded, groove-like, side rail elements designated 26 which also are arcuate in their longitudinal configuration. See FIGS. 1 and 5. The center of curvature for integral side rail elements 26 is at the position designated 30 in FIG. 1.
- Side rail elements 26 functionally co-operate with the pair of tongue-like, side rail elements designated 28 which are attached to base sub-assembly 14 by bolt fasteners 32 and which also are arcuate in their longitudinal configuration. See FIGS. 1 and 5. Rail elements 28 have the same axis of curvature 30 as, and slidably engage, side rail elements 26. Satisfactory side rail configurations other than the illustrated "tongue and groove" configuration are possible.
- Safety seat assembly 10 further includes at least one energy absorbing element which is installed in the assembly intermediate base sub-assembly 14 and seat sub-assembly 16.
- energy absorbing element takes the form of paired honeycomb core energy absorption cylinders 34.
- honeycomb core cylinder is comprised of alternate sheets of flat aluminum foil and corrugated aluminum foil wound around a mandrel (later removed) and adhesively bonded together with suitable end closures.
- other forms of energy absorbing elements that would function equivalently to honeycomb core cylinders 34 are blocks of a compressible material, such as a foamed polyurethane, or gas- or liquid-filled shock absorbers. Such devices function to absorb a portion of the imposed impact energy and spread the effect of impact over a longer period of time.
- elements 34 are each connected at one end to an extension 36 of seat pan element 24 by a conventional pivot connection 38, and at its other end to an extension 40 of the frame of base sub-assembly 14 by a like pivot connection 42. See FIGS. 4 and 6.
- removable shear pins 44 in assembly 10 intermediate the co-operating rail elements at each side of seat sub-assembly 16 and base sub-assembly 14.
- Such shear pins by their shear strength establish a threshold level only above which imposed inertial loads are transmitted from seat sub-assembly 16 and imposed on energy absorbing elements 34 to cause them to become crushed or collapsed.
- FIGS. 1 and 4 through 6 The functioning of the automotive vehicle seat 12 and safety seat assembly 10 combination can best be understood by reference to FIGS. 1 and 4 through 6.
- the center of gravity 46 of the seat/occupant portion of the combination is typically positioned above the elevation of the track comprised of slidably engaged side rail elements 26 and 28. See FIG. 1.
